It was mentioned that this script just emulates the 'Link Active Object'
This goes one better - as you can jump the Editor Cam from Scene Cam to Scene Cam
AND continue editing the Ed Cam
If you Link to Object and move the Ed Cam - you also move the Linked Object / Scene Cam
Not what's wanted

ie This script allows you to flit around all the scene cameras and freely adjust the editor cam view without affecting the selected Scene Cam. Works best with key shortcut assigned to script.
